ELNATHAN COLE,` OF LOS ANGELES, CALIFORNIA, ASSIGNOR TO OOLE MANUFACTUR- ING COMPANY, OF LOS ANGELES, CALIFORNIA, A CORPORATION OF CALIFORNIA.

GAS-HEATER.

T0 all whom it may concern:

, Be it knownthat I, ELNATHAN COLE, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful GasHeater, of which the following 1s from such a heater to the respective portions of the house to be heated. In the first style of heater mentioned a serious objection may be raised thereto .that the portable heater takes its supply of oxygen within the room and eventually burns up the greatest part of the oxygenin the room at the same time liberating in the room the obnoxious products v of combustion. Where the form of heater is employed which is placed in the" basement,

ordinarily the products of combustion are carried away. through a chimney, and the air which is used for heating the house is' heated within a chamber of the heater and does'not come in contact with the flame.

'My invention consists primarily in providing a gas heater of simple form and construction wherein the heated air from the combustion chamber of the heater is passed into the room and at the same time such air is mixed with a fresh supply of air either from the exterior of the building or from the 'i basement, and one of the main objects of my invention is to produce a gas heater of the class'described which may be installed in a house at low expense.

Referring to the drawings which are for illustrative purposes only: Figure 1 is a perspective of the portion of a building showing a heater, partly broken away, embodying the form of my invention. Fig. 2 is a vertical sectional view of the heater shown in Fig. 1 together with a portion of the floor. Fig. 3 is a sectional plan view on the line :v3- m3 Fig. 2.

The heater consists, in the form shown, of a box l open at the top and formed of an Specification of Letters Patent.

Application led December 8, 1913. Serial N o. 805,463.

v inner casing 2 and an outer casing 3 spaced apart therefrom. The space at the sides of the box between the inner casing 2 and the outer casing?) is filled with asbestos, or other suitable non-conducting material indicated at 4. y The upper edge of the outer casing 3 is turned outwardly to form a flange 5 which is secured in any suitable'manner, as by screws 6, to the underside of a floor 7, the inner casing 2`and the non-conducting material f1 extending upwardly into a suitable opening formed in the ioor 7 The bottom 8 of the inner casing 2 is provided with a'series of 'perforations 9, and the bottom 10 of the outer casing 3 is similarly provided with a series of perforations 11 of somewhat larger diameter than the perforations 9 in the bottom of the inner casing 2. v l

The upper or open end of the box 1 is provided with a common form of ioor register 12 suitably provided with closure vanes 13 and operated in the usual manner by a ""lever -13 atone end thereof. The Hoor re ister 12 is seated'within arecess formed 1n the floor so that the upper face of thefloor register is substantially flush with the upper face of the floor as is the usual custom.

The bottom 8 of the inner casing 2, and the bottom 10 of the outer casing 3 of the 'box 1 are each provided with a central openof preventing the entrance of animals or debrisv into the pipe 15.A

The box l forms a combustion chamber 17 which is provided with heating means which consists of a gas pipe 18 which extends around theend 11 of the pipe 15 being spaced a short distance above the bottom 8 of the inner casing tube. The pipe 18 is provided with a series of gas jets 19 which are' inclined inwardly and upwardly from the pipe 18 so that when the jets 19 are lighted the heat from the flames of the respective jets is directed upwardly and converges as a cone of heat, above the open the gas isl turned on by means o operatend 14 of the pipe 15 for thevpurpose'here inafter described. yThese jets, as lndicated in Fig. 2, are far enough below the open end 14 of the fair pipe to place'that open end practically above the flame zone of the burner, so that the column of fresh air which escapes from the upper end 14 V1s met and acted on, not by flames Whichwould consume its oxygen, but by the heat from said flames, which, converging into a conelike body whose apex is some distance above the upper end of the fresh air pipe, acts effectively to heat the incoming fresh air after it emerges Vfrom the top of the air` pipe without sensibly affecting its quality. One end of the pipe 18 is closed by means of a suitable cap 20 and the other end 21 of thefpipe 1S extends through the walls of the box l-and is connected by means of asuitable fitting 22 with a gas supply pipe 23, which supply pipe 23, is provided with a regulating valve 24, the stem of which extends upwardly through. the floor 7 and is provided with suitable handle means 25 above the floor 7. 4

The gasheater above described may be placed within a dwelling in any suitable manner, but -I prefer to place the same in the floor of the dwelling'close to the partition wall 28 substantially as shown in Figs.

1 and 2, in which casethe box 1 is under.,

the floor, and theregister being substantially flush with the Hoor,l the heater forms no obstructionV within they room. When it is -desired to'place the heater in o eration,

.l ing the valve 24 by the handle means 25 and a lighted match inserted throughthe registerf12, thereby lighting the jets 19. The

jets being arranged as heretofore described, direct the heat from the flames so as to converge above the open end of the pipe 15, thereby causing a' draft of air through the pipe 15 and upwardly through the open end lthereof, thence through the register 12 into the room, the products of combustion from the jets 19 being thoroughly mixed `with theair entering the box 1 through the pipe 15 thereby heating the fresh air and causing a current of heated air to pass into the room to be warmed. Air also enters the combustion chamber 17 through the openings 9 and the openings 11 in the bottom of therespective casings 2 and 3 by .means of which fresh air is .supplied directly around the jets 19 to aid in the process of combustion. Y,

Y In usingthe heater above described itis to be noted that the. room heated receives pipe `the register 12 may be closed thereby preventing any dirt or objects fromfalling into Y the combustion chamber. What I claim is:v

ing a combustion chamber; an air inlet pipe i 75 1. In a gas heater, a suitable casing formextending into said chamber with its open upper end located above the flame zone of the'burner; a burner consisting of a series of gas jets surrounding said air pipe beldw the upper end thereof and directed upwardly and inwardly with reference `t0' the same, so that the heat from their flames shall tend to converge and meet at a point above said open upper end of the air pipe;

means for supplying t-hel jets with gas; and j means for delivering air to the jets at the point of combustion.

2. `A 'gas heater adapted to be supported in a ioonlcomprising a box forming a conibustipnlfliamber"open at the top; yan air inlet pipe extending upwardly through the lbottom ofV said chamberl beyond-the flame vroue of the burner employed; a gas supply pipe in saidv chamber around said air inlet pipe below the upper end thereof; a burner consisting of a series of Vjets in said gas directed 'upwardly and inwardly toward the open end of the air inlet pipe so that the heat from their flames shall ytend to'converge-andmeet at a point above said open end of the air pipe; valve means for said gas plpe exterior to said chamber;

4and a register in the top of the combustion chamberand arranged to deliver the contents thereof into the room above thexoor, the bottom of said chamber having a series of air inlet 'perforations therein to supply air to the burning gas.

Inte'stimony whereof, I, have hereunto set my hand kat 'Los Angeles, California,*this 25th day vof November, 1913.
